Barcode

A really easy effect to get that barcode!

• Step 1 Get the Pencil-Tool and set it to 1 px and draw a line while holding shift on a new layer with black;

  

• Step 2 Go to Filter>Noise>Add Noise and set the slider to the right;

  

• Step 3 Press CTRL+T and strech it;

  

  Note:WHAT YOU CAN ALSO DO IS PRESS CTRL+L AND PUT EITHER THE BLACK SLIDER ALL THE WAY TO THE RIGHT OR THE WHITE SLIDER ALL THE WAY TO THE LEFT.

• Step 4 Set the blending-mode to multiply;

  

• Step 5 And here are some variations I came up with...
